Black and white video with Qt but not with VLC
Firstly, sorry for my english, it's not my mother tongue.
I have an USB camera named DFx 41AU02 and I wan't to use it in a Qt program. When I get video with VLC I have colored image but not with Qt example camera (black and white image).
Do you know how to resolve this problem ?
Hi and welcome to devnet,
What version of Qt are you using ?
What OS are you running ?
Are you using the Qt Camera example ?
Qt 5.12 on Windows 10
Yes i use QCamera example
Do you get the same issue if you use a Windows application with your camera ?
Qt uses the DirectShow backend IIRC for camera acquisition.

No, when I use VLC or the manufacturer's software, I have no problems.
Maybe it comes from the video format because with the manufacturer's software when I set the video format to Y800, the image is in black and white
I tried to change the video format but it doesn't change anything
Camera use YUY2 video format and it doesn't seem to be managed by Qt
Are you using the widget based camera example ? If so try again with the QML camera example.
